Hi all. I'm having what I can only describe as a very strange issue with one of the three USB ports on my Gigabyte Aero 14 laptop. Of my three USB ports, only two of them are working properly, with the last one only providing power. I've tried going into Device Manager and uninstalling all my USB drivers before rebooting, but nothing changes. Device manager still only lists two "USB Root Hub" devices. Going into the BIOS shows only two USB XHCI controllers being recognized. It's as if the third USB port does not exist at all.
Except, and here's where it gets really weird, when I plug in an external hard drive to that third port (and only an external hard drive), Windows will still recognize the drive, despite device manager still only showing two USB root hubs. No other USB device works - flash drives, mice, keyboards, fingerprint readers, etc. Only external hard drives work on that port.
I'm thoroughly baffled. I've seen the opposite happen before, where a port doesn't provide enough power to drive external drives, so everything except drives will work, but as far as I can tell, Windows just flat out refuses to acknowledge the fact that this port exists, except hard drives still work. The only thing different about the port that isn't working is that it's on the opposite side of the laptop from the other two, but opening up the back panel shows that all three ports are directly connected to the motherboard, so I'm not sure how relevant that is.
This sounds kind of similar to this old topic from a few years back, but there didn't seem to be a satisfactory resolution on it:
Any ideas?
